If you use the 'elbe control' commands (create, set_xml, build) instead of
elbe initvm submit, you can use 'elbe prj_repo upload_pkg' after a project
was created to add packages to an elbe initvm internal repository that is
automatically included while building the image. But also in this case you
need to add the package to the pkg-list of your XML. It just helps in a way,
that you don't need to build your own repository.

BTW. this repo also includes all packages built by pbuilder and is automaticly
used by pbuilder to retrieve Build-depends from.

Also patches against the docs/* repository are very welcome for all kind
of tutorials.
